When the compounds according to the present invention are used for compositions for preventing and controlling insect pests, they are generally mixed with suitable carriers, for instance, solid carriers such as clay, talc, bentonite or diatomaceous earth, or liquid carriers such as water, alcohols (e.g., methanol and ethanol), aromatic hydrocarbons (e.g., benzene, toluene and xylene), chlorinated hydrocarbons, ethers, ketones, esters (e.g., ethyl acetate) or acid amides (e.g., dimethylformamide). If desired, to these mixtures may be added emulsifier, dispersing agent, suspension agent, penetrating agent, spreader, stabilizer and the like to put them into practical use in the form of emulsifiable concentrate, oil solution, wettable powder, dust, granule,

Moreover, the mixtures may be incorporated, as necessary, with other insecticides, various herbicides fungicides, plant-growth regulating agents, synergists in formulations or applications thereof.

The amount of the compounds of the invention to be used as an active ingredient is suitably in the range of 0.005 to 50 kg per hectare although it varies depending upon the place and the seasons where the compounds are applied, manner of application, diseases and insect pests to be applied, cultivated crops to be protected and the like.

The following is a formulation proportion and kinds of various preparations of the present invention.

Test Example 9 Insecticidal test on Housefly (Musca domestica)

A 5% emulsifiable concentrate (or a 25% wettable powder) of a compound of the present invention was diluted with water to give a 500 ppm solution of the compound.

One (1) cc of the solution was dropwise applied on a filter paper placed in a laboratory dish of 9 cm in diameter. Ten larvae of housefly (Musca domestica) were released in the dish. The dish containing the larvae was kept in a thermostatic chamber of 25 ° C.

Two (2) weeks after, the number of the larvae killed was counted.

The test was conducted twice of each compound.

As a result, no emerged adult was observed at all in the dish treated with any one the following compounds. Compound Nos. 8, 9, 21, 42, 43, 45, 46, 47, 63, 65 27.
